Stopping progesterone suppositories

Ok ladies. I'm taking progesterone suppositories since I found out I was pregnant. My OB said to take til 12 weeks then I can stop. I honestly didnt need them as my levels were where they needed to be when we tested. But he prescribe them bc I needed them for my last pregnancy. So more of peace of mind for me. But my last pregnancy he said to take to 14 weeks, this time only 12 weeks. I technically I have enough refills to go longer than that but should I stop at 12 weeks or stop at 14 weeks. These are more or less a safety blanket for me if you wanna say that. Everything is going good but I somehow dont wanna jix myself. And I'll be 12 weeks Thursday with a check up that day also.
